A height adjustable auger shroud for a snow blower comprises a pair of wheels secured to a lower portion of the opposing sides of the shroud. The wheels are secured to the shroud by a pair of levers. Each lever comprises a first and second plate. The first plate is positioned against the shroud, and includes an upper arcuate perimeter having a series of notches along the upper perimeter line. The second plate is rotatably connected to the first plate, and includes a lever arm on one vertical half of the plate, and a wheel attachment on the opposing half of the plate. Actuation of the lever arm in relation to the first plate raises or lowers the wheel in relation to the shroud, thereby altering the distance between the shroud and the ground surface.
